Newly signed Celtics guard Jason Terry has already pledged his allegiance to the organization – in ink.

Terry got a tattoo of the NBA’s Larry O’Brien Trophy on his arm in the offseason before the Dallas Mavericks won their 2010-11 NBA title. He’s done it again, this time adding the Celtics’ leprechaun mascot and the O’Brien Trophy, he posted in a photo on his Twitter account, ProBasketballTalk pointed out.

The tattoo is looked at as Terry calling his shot. Without the help of the veteran guard last season, the Boston Celtics pushed the Miami Heat to Game 7 of the Eastern Conference finals. With the additions of Terry and Courtney Lee, Boston will attempt to take another shot.

It will do so without Ray Allen, a key cog in the team’s “Big Three.” But Rajon Rondo, Kevin Garnett and Paul Pierce remain on the roster, and forwards Jeff Green and Chris Wilcox will return to the court after both sat out with heart ailments last season.

Boston could make a serious push for the title next season, and if it does pull out a finals win, there’s no telling what version of the O’Brien Trophy Terry would add next.
